Don't even try to wrap your head around eternity. It'll melt your brain. Equally terrifying and brain-melting (to me, anyway) is to consider the thought of NOTHING. What if this universe never came to be? What if there were no light, no darkness, no space, no time, nothing? Why is there anything? It seems more logical that there should be nothing. But there isn't. We are. Take comfort in that fact. And the fact that we have a much grander divine destiny, if we choose it. Eternal progression is a true principle. IF you will choose it and not choose damnation (defined as an end to learning and growth and progression). Jesus Christ is the only way.
